DiNfrrus, Sweet. From dinetos, that may be 

 twined ; in allusion to the habit of the plants. 

 Linn. 5, Or. 1, Nat. Or. Convolvulacece. A 

 very ornamental genus ; the perennial species 

 thrive well in any rich light soil. Young cut- 

 tings, planted in the same sort of soil, under a 

 glass, in heat, will soon root. D. racemisa grows 

 very fast in a sheltered situation, and is well 

 adapted to make a good covering for a tempo- 

 rary arbour. It is increased from seed, which 

 is ripened in abundance. Synonymes : 1, Po- 

 rana paniculata ; 2, P. racembsa.

 des Oarystinus, an ancient Greek botanist. 

 Linn. 17, Or. 4, Nat. Or. Fabacece. A twining 

 shrub, growing in any common soil, and in- 

 creased by cuttings in sand, under a glass, in 

 heat. Synonyme: 1, Ddliclios mdllis—mdllisl. 



D16BIA, Linn. From diodos, a passage ; many 

 of the species grow by the way-sides. Linn. 



4, Or. 1, Nat. Or. Cinchonacece. A genus of 

 rather pretty trailing shrubs, of simple culti- 

 vation. A light soil suits them best ; and 

 cuttings, in the same kind of soil, root freely 

 if placed in heat.

 mens and those with the seed-bearing organs 

 growing on different plants.

 daughter of Phorbas. Linn. 19, Or. 2, Nat. Or.

 same kind of soil, under a glass. Synonymes:

DIon, Lindley. Bis, two, and oon, an egg, each 

 scale bearing two ovules. Linn. 22. Or. 11, 

 Nat. Or. Cycadacece. A singular Mexican 

 genus ; the plant introduced to this country, 

 and presented to the Horticultural Society, had 

 a simple stem, like that of a Zamia, but buried 

 in wool ; bearing deep and light green pinnated 

 leaves. A cone which accompanied the plant, 

 consisted of woolly rigid two-lobed scales, col- 

 lected into a cone the size of a child's head, 

 bearing on each lobe a single nut about as large 

 as a chestnut,

DionAa, Linn. Dione, one of the names of 

 Venus. Linn. 10, Or. 1, Nat. Or. Droseraceie. 

 This is a very singular little plant in respect 

 to its leaves, which are of an anomalous form, 

 and have a curious motion, by which thdy 

 catch insects ; whence the specific name, Mu- 

 sclpula, a fly-trap. The petiole of the leaf is 

 winged. The extreme part is that which acts 

 as a trap. As soon as the insect enters, the 

 lobes of the leaf fold together, and remain so 

 as long as the insect continues to struggle ; 

 but as soon as it is quiet, the leaf opens and 

 permits it to escape. The plant thrives best 

 in small pots, in peat earth, and some dwarf 

 species of moss placed underneath in the pot ; 

 the pots should then be placed in a pan of 

 water, and set in a cool place in the stove, 

 with a glass over them, but not close, else 

 they will be liable to damp. Seeds are some- 

 times produced, by which they may be in- 

 creased, but the readier way is to divide the 

 plants at the root. It has also been found, 

 that if a leaf be taken off, and placed on 

 damp moss, it will emit a young plant from 

 its edge.
